中药材硫磺熏蒸后有害物质及其危害研究进展

硫磺熏蒸是基层中药材生产中常用的防腐、防虫、杀菌方法,广泛用于中药材和食品的加工贮藏。近年来,由于部分商家片面地追求经济效益,为了保水增重及美化外观色泽,过度使用硫磺熏蒸,导致二氧化硫（SO₂）及有害重金属等的残留,严重影响了中药材品质。该文从硫磺的种类及用途入手,对硫磺熏蒸方法、硫磺熏蒸的中药材品种、硫磺熏蒸中药材的有害物质残留及其危害进行概述总结,深入探讨硫磺熏蒸中药材后有害物质的残留对人体健康的危害,为中药材硫磺熏蒸方法的规范化及替代技术的选择提供理论依据。     

中药熏洗治疗膝骨关节炎早期合并半月板损伤疗效观察

目的：观察中药熏洗方热敷一号对膝骨关节炎（KOA）早期合并半月板损伤治疗的疗效。方法：将75例 KOA早期合并半月板损伤患者随机分为两组,治疗组采用中药熏洗治疗;对照组单纯口服西药塞来昔布胶囊。结果：通过KOOS膝关节损伤和骨关节炎结果评分对治疗前后评估,两组治疗前后均有显著性差异（P〈0.05）,总有效率治疗组大于对照组。结论：中药熏洗治疗膝关节骨性关节炎早期合并半月板损伤疗效显著,疗程短,值得临床推广。

含有低浓度肠安Ⅰ号制作的安慰剂对腹泻型IBS大鼠内脏高敏感性的影响

目的研究低浓度肠安Ⅰ号制作的安慰剂对番泻叶灌胃联合传统束缚应激诱导腹泻型肠易激综合征（IBS）大鼠模型的影响。方法采用番泻叶灌胃联合传统束缚应激诱导腹泻型IBS大鼠模型,将实验动物分为8组：正常组、模型组、肠安Ⅰ号高、中、低剂量组、含有低浓度（5%、10%）肠安Ⅰ号的安慰剂两组和阳性药对照组。观察各组大鼠在20、40、60、80mmHg下行直肠扩张,采用腹壁撤退反射（AWR）评分测定各组大鼠在20、40、60、80mmHg直结肠扩张压力下疼痛反应,观察本安慰剂对IBS大鼠内脏高敏感的影响。结果番泻叶灌胃联合传统束缚应激诱导腹泻型IBS大鼠模型在造模后第1天各实验组和用药结束后模型组明显增高（P〈0.05）,显示造模成功。中药对照药肠安Ⅰ号能降低IBS大鼠内脏敏感性的AWR评分（P〈0.05,P〈0.01）,且有一定的量效关系。安慰剂组不能降低其AWR评分（P〉0.05）。结论肠安Ⅰ号高、中、低剂量组对番泻叶灌胃＋传统束缚应激诱导腹泻型IBS大鼠的内脏高敏感性有一定的调节作用,含有低浓度肠安Ⅰ号制作的安慰剂对IBS大鼠的内脏高敏感则没有调节作用。     

The Efficacy of an Herbal Medicine, Carmint, on the Relief of Abdominal Pain and Bloating in Patients with Irritable Bowel Syndrome: A Pilot Study

Carmint contains total extracts of Melissa officinalis, Mentha spicata, and Coriandrum sativum, which have antispasmodic, carminative, and sedative effects. As abdominal pain/discomfort and bloating are commonly observed in patients with irritable bowel syndrome, we decided to evaluate the effectiveness of Carmint in relieving these symptoms in irritable bowel syndrome patients. We randomly assigned 32 irritable bowel syndrome patients to receive either Carmint or placebo, plus Loperamide or psyllium (based on their predominant bowel function), for 8 weeks. T-test analysis of the results showed that the severity and frequency of abdominal pain/discomfort were significantly lower in the Carmint group than the placebo group at the end of the treatment (P=0.016 and P=0.001, respectively), as were the severity and frequency of bloating (P=0.02 and P=0.002, respectively). This pilot study suggests that Carmint plus loperamide or Carmint plus psyllium (depending on the irritable bowel syndrome subtype) might be effective in these patients.     

Toxic acute hepatitis and hepatic fibrosis after consumption of chaparral tablets

In this report we describe a young, previously healthy woman who developed severe acute hepatitis after consumption of chaparral tablets, a commonly used herbal product. In this case, the elimination-rechallenge event and the exclusion of other possible aetiologic factors strongly supported true causality between the herbal product and the liver damage. Primary liver biopsy showed severe toxic hepatitis consistent with previous reports of chaparral-induced liver damage. Later, 6 months after the liver function tests had normalized, permanent hepatic fibrosis could still be seen.

采用中药保留灌肠联合吡喹酮治疗血吸虫性结肠病并观察其临床疗效，结果显示，经过1～2个疗程治疗后总有效率可达95％。     

中药脱敏剂治疗牙本质过敏的临床疗效观察

目的:观察中药脱敏剂治疗牙本质过敏的临床疗效。方法:选取牙本质过敏患者126例,随机分为研究组64例(患牙172颗)、对照组62例(患牙158颗),分别使用中药脱敏剂和氟化钠甘油进行治疗。观察2组患者在治疗后即刻、3个月后、6个月后的疗效,并进行统计学分析。结果:2组疗效比较有显著性差异(P<0.01)。结论:中药脱敏剂可有效治疗牙本质过敏,且使用方便,疗效相对持久。
